### ⭐⭐⭐⭐⭐ Fast delivery

It comes fast as I needed.

### ⭐⭐⭐⭐⭐ Works great
*by R***B on May 4, 2019*

Great product great price

### ⭐⭐ Becareful buying such large quantitiy
*by A***I on May 9, 2009*

Because the description of this product was extremly poor, i bought a large quantity not knowing you need only a tea-spoon for a single tree (every 3 months)... now i have over-paid and have enough to last me 1000 years. Haven't seen if the product works, but assuming it does, purchase the 1lb or smaller container and save yourself $100.
